Anybody Know About Electronic Drum Connections?

I bought a Lekato compact kit. I love it but the foot triggers are awful squares with an obvious lack of that real pedal use/feel. So, I switched then out with a Simmons hat and kick setup.

The Lekato has a TS 'Kick Switch' connection for the square. It doesn't work for the Simmons kick. But there is a TRS 'Kick Drum' connection that does work with the Simmons.

The Lekato has a TS 'Hi-hat Control' connection that does not work with the Simmons hi-hat. I thought if I got a TS to TRS adapter that it would hit the connection point and solve the issue. It did not seem to work. The work around I currently use is to only plug it in about half way.

Does anyone have any ideas on how to solve this problem? If not I am just going to have to zip tie/tape setup so it plugs in at the right point that everytime.
